Analysis and simulation of incident photon to current efficiency in dye sensitized solar cells

Conversion of solar energy into electricity is a challenging issue of today’s renewable energy. Electrochemical dye solar cells (DSC), based on nanostructured TiO2 particles are a very promising class of photovoltaic devices [6]. The mechanism beyond the conversion of the light is quite different from any other solid state solar cell, resulting from the interplay of a fine tuning of the energy levels of the cell components and a delicate fabrication process. This complexity needs a reliable transport model, able to catch the device as a whole and applicable to experimental set up. We developed an extension of TiberCAD [7] code to simulate such kind of devices and compared the calculation with incident photon to current efficiency (IPCE) measurements.
